C++ or C++0x - Which is a better standard? [closed]

As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, visit the help center for guidance. Closed 12 years ago.

So I've been trying to do some research and would like the opinions of other developers on this topic. I am an experienced C++ programmer and have been using the current C++ standard 开发者_开发知识库for some time. I have been reading articles that "C++0x will undoubtedly become the new standard." How far off are we does everyone think from making the switch to a whole new programming standard? Also, which, in your eyes, is a better standard? From how I understand it, C++0x will come with more standard libraries making development easier without many more dependencies. Please help me to catch up!

Thanks!

Dennis M.

It would be pretty sad if the next version of C++ were quantitatively worse than the current one. The entire point of the new revision is to improve things.

Well, it depends.

The current C++ standard (C++03) is currently "better" because most of the latest C++ compilers and standard library implementations conform fairly well to the standard. Yes, there are issues, but most of them are very well known (e.g., hardly any compiler supports export) or are fairly easy to work around.

Support for C++0x is pretty patchy right now. Different compilers support different parts and there have been pretty major modifications made to it over the last year, so compilers that did provide early support for some features are now "buggy" if you consider their conformance to the latest drafts.

Going forward, though, C++0x will be a huge improvement over C++03. Major features like the concurrency memory model and the standard threads and atomics libraries are extremely important for the future of the language. Move semantics will make it easier to write clean, high performance code. Most of the new language features will make developing in C++ a more enjoyable experience.

"C++0x will undoubtedly become the new standard" is an understatement. C++0x is the draft of the new standard. Parts of it are available now in compilers like G++ 4.5.

It is impossible for C++0x to be qualitatively worse than the current C++ standard, because one of the essential things about the new standard is that it is fully backward compatible. If there are bad parts, you can just avoid them. (Of course, that doesn't mean that new features in C++0x can't be used to create really bad code that you'll have to deal with, but if you're coding on your own, you can always choose to avoid C++0x features that are worse in your opinion.)

Depends on what you mean by "better". If you mean "More likely to work with whichever compiler I'm using at the moment", then the old standard will certainly be better, with a little boost thrown in.
